Hi Fernanda,
Thanks for your reply. I am taking 15C as ambient temperature since the operating is positive value (43C). In case, if the operating temperature is negative value (-), then i will have to take 32C as installation temperature. (this is suggested by our seniour engineer).
But, I think i should not consider many thermal cases here like T1, T2, T3 & T4 as you have suggested. incase, if i have two operating cases with one temperature above ambient and another case below ambient, then i have to go for taking different thermal cases as you suggested. But, since there is only one operating condition in my system, i think changing the ambient to 15C and take one thermal case for maximum operating temperature and analyse the system is adequate.
If you have different openion in this regard, please suggest me fernanda.
or anyone else have other openion that contradicts with mine, please cite out here. I would like to explore this further. Thanks in advance to all of you.
